Abstract

A light emitting diode (LED) warning signal light, the warning signal light comprising an array of light sources configured on a light support and in electrical communication with a controller and a power supply, battery, or other electrical source. The warning signal light provides various colored light signals for independent use or use by an emergency vehicle. These light signals may include a stationary light, strobe light, revolving light, and an oscillating light. Additionally, the warning signal light may be capable of displaying symbols, reverse characters, or arrows. Preferably, rotating and oscillating light signals are produced by sequentially illuminating columns of LED'"'"'s on a stationary light support. However, the warning signal light may also be rotated or oscillated via mechanical means. The warning signal light may also be transportable for easy connection to a stand such as a tripod for electrical connection to a power supply as a stand-alone warning signal.

Claims

1. A combination multiple warning signal light system and motorized vehicle, the warning signal light system comprising:

a) a plurality of light supports engaged to the vehicle, each of the plurality of light supports having one or more light emitting diodes; and

b) at least one controller in electric communication with the light emitting diodes, the controller constructed and arranged to activate the light emitting diodes thereby producing at least two different types of visually distinct warning light signals, wherein the at least two different types of visually distinct warning light signals are produced simultaneously, said light emitting diodes receiving power from a power source.

2. The combination of claim 1, wherein the at least two different types of visually distinct warning light signals are produced in at least one combination.

3. The warning signal light of claim 1, each of said light supports comprising a front side wherein the controller is configured to selectively activate the light emitting diodes to create multiple light signals on each front side.

4. The combination of claim 3, the at least one controller constructed and arranged to activate the light emitting diodes on each of the front sides independently of each other, whereby the at least two different visually distinct warning light signals are illuminated on the front side of at least one of the plurality of light supports at any moment.

5. The multiple warning signal light of claim 4, wherein the at least two different types of visually distinct warning light signals are produced simultaneously.

6. The multiple warning signal light of claim 4, wherein each of the at least two different types of visually distinct warning light signals are produced on different front sides.

7. The combination of claim 4, the at least one controller further constructed and arranged to activate the light emitting diodes on each of the front sides independently of each other, whereby different visually distinct warning light signals are simultaneously illuminated on at least two of the front sides at any moment.

8. The combination of claim 4, the at least one controller constructed and arranged to activate the light emitting diodes on each of the front sides with a predetermined common warning light signal.

9. The combination of claim 7, the at least one controller further constructed and arranged to activate the light emitting diodes on each of the front sides independently of each other whereby different visually distinct warning light signals are simultaneously illuminated on at least two of the front sides at any moment.

10. The combination of claim 4, each of said light supports further comprising a back side having a plurality of light emitting diodes.

11. The combination of claim 8, the at least one controller further constructed and arranged to activate the light emitting diodes on each of the back sides with a common warning light signal for illumination of at least two of the back sides at any moment.

12. The combination of claim 10, the at least one controller further constructed and arranged to activate the light emitting diodes on each of the back sides independently of each other, whereby different visually distinct warning light signals may be simultaneously illuminated on at least two of the back sides at any moment.
